Filed Mama, 1961, Ser. No.95,715 4 Claims. (Cl. 83209) This .inventionrelates to a paper feeding and cutting machine, and more particularly toa machine for selecting and supplying paper, such as sensitive paper, ofdesired Width from available supplies of different widths, and cuttingthe selected paper to the desired length to accord with a master sheetwith which the same is to be used.

Reproduction machines for rapid production of copies from negatives ormaster sheets are in common use. No satisfactory equipment is availablefor supplying the copy paper of a width and length .to conform to themaster sheet with a minimum .of Waste and as called for by the size ofthe master sheet.

The feeding of the master and sensitive sheets to the copying machine iscurrently performed as a manual operation in which the original ispicked up and a selection is made by the operator of a copy sheet of thedesired size from a stock of copy material cut to size. The original andcopy sheet are aligned and the two sheets are fed together into themachine. In most instances, these operations cannot be performed withsuflicient rapidity to utilize the capacity of the reproductionequipment and there is no accommodation to still different sizes ofmaster sheets.

While some efforts have been made to feed a continuous strip of copypaper into the machine accompanied by the master sheet, this does notpermit of .accommodating the print to the size of the master sheet,results in excessive waste of the sensitized material, and requiresexcessive cutting subsequent to severing from the strip to trim the.copy sheet to size.

It is the principal object of the present invention to provide a machinefor delivering an original and copy sheet of correct size in alignmentto a machine for producing copies in which a measurement is made of thewidth of the master sheet, a selection is made of copy sheet material ofsuitable width, the master sheet and copy strip are aligned, the mastersheet and selected copy strip are advanced, a proper length of copysheet is transversely severed from the selected copy strip, and themaster sheet and transversely severed copy sheet are advanced togetherto the reproduction machine.

It is a further object of the present invention to provide a paperfeeding and cutting machine having a plurality of rolls of printing orcopy paper of differing widths therein, together with simple buteffective structure for measuring the width of the master or originalfrom which a copy is to be made, and selecting and causing the advanoeof material of appropriate width to conform to the width of the mastersheet.

It is a further object of the present invention to provide a paperfeeding and cutting machine having a plurality of rolls of printingorcopy paper of differing widths therein, together with structure forselecting a copy sheet of proper width and aligning the leading edge ofthe original and the leading edge of the selected copy sheet.

it is a further object of the present invention to provide a paperfeeding and cutting machine having provisions for simultaneouslyadvancing the original or master sheet and a-strip of copy sheet withthe leading edges of the original and the copy sheet aligned, andsevering the copy sheet at a length determined by the length of theoriginal or master sheet.

It is a further object of the present invention to provide a paperfeeding and cutting machine having a plu- Platenteol May .11, 1955 ICCrality-of sources of paper of different widths and simple but effectivetransverse paper cutting mechanism acting on the selected strip of papenIt isa'further object of the present invention to provide a paperfeeding and cutting machine in which the measuring, selecting, edgealignment, transverse severing, and feeding are carried out as acontinuous and automatic operation.

The gage plate 58 preferably has a plurality of detector pockets 66provided therein at predetermined transversely spaced intervals, andpreferably at each inch transversely of the gage plate 58 and alignedwith the markings on the scale 61. Each of the detector holders 64 and65 carries a detector element which may be a microswitch 67, 67a, 67b,67c, 67d, actuated by a switch arm 68. Each arm 68 normally extends intoa pocket 66 unless moved outwardly therefrom by the master sheet cominginto contact therewith, as hereinafter explained.

In the space below the gage plate 58 an anvil mounting bar 70 isprovided secured at its ends to the plate 58 and carries an anvil plate71, preferably of nylon, on the lower face thereof for aiding intransverse strip severing, as hereinafter explained.

Upper and lower stock guide plates 69 and 69a are provided, the upperguide plate 69 extending downwardly from the master sheet guide plate 59to the anvil plate 71. The space between the stock guide plates 69 and69a faces to the entrance to the conveyor belts 45 and 46.

In accordance with the number of rolls of copying paper which it isdesired to mount or store in the machine for availability for selectionand supporting of stock,

cradle rolls 72 are provided for supporting rolls of sen-- sitized orcopy paper for feeding. The cradle rolls 72 are rotatably supported attheir ends in the end frame plates 24, access openings 73 being providedin the frame plates 24 for the insertion of a roll of sensitized or copypaper.

As shown, and merely by way of illustration, four sets of cradle rolls72 are provided. Each set of cradle rolls 4 72 preferably has a stockholder bar 74 associated therewith with clamps 75 adjustably mountedthereon at one or both ends and each having an upwardly extending arm 76for end abutment against the paper roll to limit the sidewisedisplacement thereof.

Each set of cradle rolls 72 also has contiguous thereto antidrag rollers77 about which the paper from the paper supply rolls is directed. Therollers 77 are rotatably supported in the end frame plates 24.

Each set of cradle rolls 72 has a pair of contacting stock feed rollers78 and 79 associated therewith. The rollers 78 and 79 are respectivelycarried on shafts 80 and 81 journalled in the end frame plates 24, andthe shafts 80 and 81 are moved in unison by gears 80a and 81a securedthereto. One of the shafts, such as the shaft 81, can have a hand wheel81b thereon for manual turning to initially adjust the paper to beadvanced thereby.

One of the stock feed rollers 78 and 79, such as the roller 78, isdriven in any desired manner, such as by electrically driven gear motors82, 82a, 82b, 820, each connected thereto through an overrding clutch83.

A spring clip 84 can be provided engaging each of the shafts 80, thespring clips 84 each being carried on pins 85 on the end frame plate 24,each acting as a brake and accommodating various thicknesses of stock.

Sensitized paper feed passageways are provided from each set of stockfeed rollers 78 and 79 to the anvil plate 71, formed by guide plates 86in converging relation toward the anvil plate 71. The guide plates 86are provided with guiding ribs 87 and have disposed therebetweenadvancing rolls 88 carried on shafts 89 journaled in the end frameplates 24. The advancing rolls 88 preferably have friction facings 8811over portions of their circumferences so that upon rotation of any ofthe rolls 88, the sheet material is prevented brom bunching orcollecting in the passageways between the guide plates 86.

The shafts 89 are connected to and selectively driven by rotarysolenoids 90, 90a, 90b and 900.

It will be noted that the centers of the feed rolls 78 and 79, as seenfrom the ends, are arranged on a common center so as to have the meetingportions of the rolls 78 and 79 all at the same distance from apredetermined line on the anvil plate 71 to insure uniformity of linearpaper feed from each roll of sensitized or copy paper.

The paper cut-off mechanism, shown in detail in FIGS. 4, 5 and 6,preferably includes, for coaction with the anvil plate 71, previouslyreferral to, a cutter bar 91 having a steel rule 92 secured thereto by aplurality of studs 93 extending through slots 94 in the rule 92.

The cutter bar 91 is pivotally connected by guide links 95 to asupporting bar 96 which is supported by the end frame plates 24. Inorder to move the cutter bar 91 toward the anvil plate 71, an actuatinglink 97 is provided.

The actuating link 97 is connected to an eccentric pin 98 which isadjustably mounted by studs 99 extending through elongated slots 100 ina pin carrying head 101. The studs 99 extend into a driving block 102which is secured to a shaft 103, the shaft 103 in turn being connectedthrough a single revolution clutch 104 controlled by a solenoid 105 to aflywheel 106. The flywheel 106 has a groove 107 on the periphery thereoffor engagement by a driving belt 108 which is in engagement with adriving pulley 109 on a shaft 110 of a continuously operating electricmotor 111. The motor 111 is supported by the end frame plate 24 at theright.

The structure for selectively controlling the paper feed and papercutoff will now be described.

The microswitch 67 in the detector holder 64( see FIG. 7) has aconductor 115 extending from a suitable source of electrical energy to amovable contact 116, which contact 116 is controlled by the arm 68 ofthe microswitch 67. The arm 68 is actuated and moved to microswitchactuating position by the presence of the master sheet in engagementtherewith. The microswitch 67 has a pair of fixed contacts 117 and 118,the contact 117 being connected by a conductor 119 through a singleimpulse pass device 120, commercially available .under the namePulse-Pak, and through an adjustable time delay .relay 121 tooneterminal of the winding of the clutch operating solenoid 105. The otherterminal of the Winding of the solenoid 105 can be connected by asuitable conductor 122 toground.

The detector holders 765 are each provided with microswitches 67a to67d, respectively, the number being dependent upon the number of rollsof sensitized paper carried on the respective groups of cradle rolls 72.

The microswitch 67a has a pair of fixed spaced contacts 123 and 124, andhas a movable contact 125 which is connected by a conductor 126 to anysuitable source of electrical energy. The movable contact 125 of themicroswitch 67a is controlled by its actuating arm 68, Which is in turnactuated by the presence of the master sheet in engagement with its arm68. The contact 124 of the microswitch 67a is connected by a conductor127 to the movable contact 128 of the microswitch 67b which ,microswitch67b is positioned by its arnr68.

It will be noted that unless and until the microswitch 67a has itsmovable contact 125 moved into engagement with the fixed contact 124,that no energizing circuit is set up therethrough.

The microswitch 67.5 has a pair of fixed spaced contacts 129 and 138 forselective engagement by the movable contact 128. The contact 129 isconnected by a conductor 131 to the rotary solenoid 90 for rotating theshaft 89 and the roller 88-thereon and by a conductor 132 to the motor82 for actuating the rolls 78 and 79. The rotary solenoid 90 and themotor 82 are connected by a conductor 133 to ground.

The contact 138 of the microswitch 67b is connected.

by a conductor 134 to the movable contact 135 of the microswitch 670which contact 135 is positioned by its arm 68. The microswitch 670 has apair of fixed spaced contacts 136 and 137 for selective engagement bythe movable contact 135.

The contact 136 is connected by a conductor 138 to the next rotarysolenoid 90a for rotating the next shaft 89 and roller 88 thereon and bya conductor 139 to the next rotor 82a for actuating the next set ofrolls 78 and 79. The rotary solenoid 90a and the motor 82a are connectedas before by the conductor 133 to ground.

The contact 137 of the microswitch 67c is connected by a conductor 140to the movable contact 141 of the microswitch 67d which contact 141 ispositioned by its arm 68. The microswitch 67d has a pair of fixed spacedcontacts 142 and 143 for selective engagement by the movable contact141. The contact 142 is connected by a conductor 144 to the next rotarysolenoid 98b for rotating the next shaft 89 and the roller 88 thereonand by a conductor 145 to the next motor 82b for actuating the next setof rolls 78 and 79. The rotary solenoid 98b and the motor 82b areconnected as before by the conductor 133 to ground.

The contact 143 of the microswitch 67d is connected by a conductor 146through branch 147 to the next rotary solenoid 90c for rotating the nextshaft 89 and the roller 88 thereon, and through branch 148 to the nextmotor 82c for actuating the next set of rolls 78 and 79. The rotarysolenoid 98c and the motor 820 are connected as before by the conductor133 to ground.

The mode of operation will now be pointed out.

The motor 111 is energized to rotate the flywheel 186 and the motors 35and 41 are also energized to drive the feed rollers 31) and 31 and thefeed rollers 37 and 38.

The motor 43 is energized to operate the drive rolls 47 and 54 and tooperate the upper and lower conveyor belts 45 and 46. p

The machine is now ready for use. If now a master sheet is advancedrearwardly over the platform or feed table 17 with its margin along theinner end wall 18 at the left as a gage, the master sheet strikes andmoves the 8 actuator arm 68 of the microswitch67 to move the movablecontact 116 to the unenergized contact 118 so that the cutter bar 91 andrule '92 are in their retracted positions preliminary to but ready formovement for subsequent cutting, as hereinafter explained.

One or more of the actuating arms 68 of the microswitches 67a, 67b, 67c,and.67d, will be moved, dependent upon the width of the .master sheet toselect the proper roll stock widthfor sensitized paper delivery.

Assume a relatively narrow Width of master sheet but sufficient to movethe arm '68 of the microswitch 67a, then .the minimum widthof roll stockwill be made available in the manner to be explained.

The movement. by the arm 68 of the movable contact 125 of themicroswitch 67a to engage the contact 124 will set up an energizingcircuit through the conductor 127, the contact 129, and the conductors'131 and 132 to the solenoid 98 and the motor 82.

Upon energization of the motor 82 the shaft rotated thereby is effectiveto rotate the feed roller '78 thereon, the feed roller 79 being drivenin unison by the gears 80a and 81a. At the same time, energization ofthe rotary solenoid is effective to rotate the shaft 89 and theadvancing roll 88 thereon. Paper from the roll supported on the cradlerolls 72 and threaded around the antidrag roller 77, is advanced by thefeed rollers 78 and 79 and in the passageway between a pair of guideplates 86 past the anvil plate 71' to meet the leading edge of themaster sheet at the entrance to the .conveyor belts 45 and 46. Themaster sheet and paper from the sensitized roll advance together betweenthe conveyor belts 45 and 46. This feeding continues until the trailingedge of the mas ter sheet permits the actuating arm 68 of themicroswitch 67 to be returned so that the movable contact 116 of themicroswitch 67 will engage with the fixed Contact 117' and set up apaper cutoff energizing circuit through the conductor 119, the impulsecontrol unit 120, the time delay relay 121, and the solenoid to actuatethe clutch 104 to connect the shaft 183 for effecting movement of thelink 97 to move the cutter bar 91 and the rule 92 toward the anvil plate71 to sever the roll stock as determined by the delayed timed operationof the cutter bar 91.

The severed sensitized sheet is fed with the master sheet by theconveyor belts 45 and 46 to the machine at which the exposure ordeveloping action is accomplished.

If wider roll stock is called for by movement of the actuating arm 68 ofthe microswitch 67b, an energizing circuit is set up through the contact130, the conductor 134, the movable contact 135, and the contact 136,and conductors 138 and 139, to energize the rotary solenoid 98a and themotor 82a to feed stock from a roll of greater Width. It will be notedthat if the rotary solenoid 98a and the motor 82a are energized, therotary solenoid 90 and the motor 82 are not energized by reason of theselection by the movable contact 128.

If still wider roll stock is called for by movement of the actuating arm68 of the microswitch 67c or the microswitch '67d, energizing circuitswill be set up similar to those previously explained for operating thefeed rollers 78 and 79 to supply the proper width of sensitized paper.

The leading edge of the paper which has been severed is available foradvance if and when called for by the master sheet whose Width isrelated to the stock required. In the event that the same or a differentwidth is called for by the next master sheet, the appropriate gear motor82 to 82c and rotary solenoid 99 to 980 for feed are actuated to feedthe sensitized sheet of selected width and for longitudinal severing asdetermined by the distance between the leading and trailing edge of themaster sheet and the timing as set at the time delay relay 121.
